Some basic help with "Class"

Claus Mygind

2005-09-22, 9:23 am

I would like to make a call to one location for the options in a select box
each time I add a select box to a form so the list can be more easily
maintained. see example below (in this example the call is made to a
function within the class "MyCGISession"). How can that same call be made
to a function located outside this class? The problem I am having is with
the reference to "with (this.fOut)".

Class MyCGISession of CGISession from "WebClass.cc"

// my own external function class "contains function called StateName( )"
set procedure to ConvertData additive

function streamBody

with (this.fOut)
puts('<BODY ')

puts(' <td>State')

cValue = [<option value="] + c["ST"].value + [" SELECTED>] +
StateName(c["ST"].value) + [</option>]

puts(' <select name="ST">')
puts( cValue)
//////////////////////////////////////////////
//my question is here. How do I make this call to an outside file that
can be reused on every form that has this select box?
class::writeStates()

///////////////////////////////////////////////
puts(' </select></td> ')

endwith

function writeStates()
with (this.fOut)
puts('<option value="AK">Alaska</option>')
puts('<option value="AL">Alabama</option>')
puts('<option value="AR">Arkansas</option>')
puts('<option value="AZ">Arizona</option>')
puts('<option value="CA">California</option>')

Leave out the "class::" indicator.

Pass a parameter referencing the object:

WriteStates( this )

function WriteStates( oObj )

> with (this.fOut)

And rather than "this.fOut", you would use:

oObj.fOut

Thanks Ken,

Just what I needed. This will really make program maintenance easy now.
